From an article printed earlier:
"Today the United Farm Workers endorsed Hillary Clinton. Although they appreciate Senator Sander's contributions to the economic debate, they are are not feeling the bern because of his work against their chances for a path to immigration reform. They are also very concerned by his exploitation and willingness to put aside his professed aversion to the guest worker program as long as it benefits his home state of Vermont.
Sen. Sanders voted against the Kennedy-McCain bill and led the push for amendments that killed the measure because he opposed the conditions pushed by business interests for guest workers, he said during the Feb. 11 debate.
But Sen. Sanders' opposition to abusive guest worker programs didn't extend to a bill he cosponsored in 2011, to allow agricultural guest workers into his home state's largest farm sector -- Vermont's dairy industry... So the Sanders-backed measure could have let dairies replace all current domestic farm laborers with foreign guest workers --
with the same damaging impacts on wages and working conditions for both domestic and foreign guest workers Sen. Sanders decried in other industries."
